Investigation and validation of a Francis turbine at runaway operating conditions

Trivedi, Chirag; Cervantes, Michel; Gandhi, BK (Journal article; Peer reviewed, 2016)

Hydraulic turbines exhibit total load rejection during operation because of high fluctuations in the grid parameters. The generator reaches no-load instantly. Consequently, the turbine runner accelerates to high speed, ...
Numerical Simulation and Validation of a High Head Model Francis Turbine at Part Load Operating Condition

Goyal, Rahul; Trivedi, Chirag; Gandhi, BK; Cervantes, Michel (Journal article, 2017)

Hydraulic turbines are operated over an extended operating range to meet the real time electricity demand. Turbines operated at part load have flow parameters not matching the designed ones. This results in unstable flow ...
